I tried to move some parts into a new level but when I do the lighting gets messed up. How do I fix it?

I had a few places where the player would go like a forest then to a desert, and a tutorial level for example. I didn’t want the player to see the other places while they were in another one so I was going to move each place into their own level and then have it just teleport you to that level. Whenever I copy and paste a place into a new level the lighting is really weird and I don’t know how to fix it. I am a student and this is our first big project in ue4.

Some warnings I have gotten:

  1. Performance Warning No importance volume found and the scene is so large that the automatically synthesized volume will not yield good results. Please add a tightly bounding lightmass importance volume to optimize your scene’s quality and lighting build times

       - I looked on forums that other people have posted and put in an importance volume over the entire scene but it didn't seem to do anything except make the warning go away.

  2. Large actor receives a pre-shadow and will cause an extreme performance hit

Here are some pictures of how the lighting is supposed to look and how it looks when copy and paste into the new level. (it wouldn’t let me post pics directly into this post so I added links)

I hope this helps. Thanks.

Yea. That was one of the first things I did. And then I added the importance volume and then did it again but it didn’t change anything

You have to rebuild light in the new level after the copy. Have you done that?

4

These are separate levels, right? Or are you mixing them with level streaming or something?..

5

I think they are seperate. Im not really sure what level streaming means because i’m still relatively newish. I attached a picture of my ue4 so you can see for yourself. My level where I made everything first was FirstPersonExampleMap and then I copied and pasted things into their own levels.

Ok, then you’re not streaming ( you would know ).

How are doing the copy/paste? Two copies of the editor?

7

I am just clicking on the thing I want and then using ctrl c ctrl v. I selected everything that I wanted by holding shift and left clicking.

Do you think the problem is because I pasted everything in one go in the new level all at once?

9

Sounds ok. So you copy and then open the other level and paste?

10

ya. I haven’t changed anything between the two. i just copy and pasted. but ill give the other stuff a go.

Thanks for trying!

Ah… select the skylight and the look in the details panel.

EDIT: You skylights are in different positions, so probably is the directional light. That can make a difference ( as with fog etc ).

Here is the skylight from the main level

Here is the skylight from the new level

The only differences I’ve found where they had a different location and one was static and one was stationary. does changing those things effect anything? Should I make the new level skylight exactly the same as the Main level one?

For the new level, I just clicked make new level and then default. . I didnt mess with the skylight at all and I dont remember messing with the skylight in my Main level if I did.

13

yup. thats what i did. Do you think it was because i copied eveything at once? Also i found this link: Managing Multiple Levels | Unreal Engine Documentation

Maybe that would work?

. I was talking to a friend and they said ue4 can be weird when copying and pasting a certain way.

14

Yes, maybe give that a go. But what you were doing also sounds fine actually. The only thing I can think, apart from building light, is making sure you have the same lighting conditions, of course…

15

Ok, one last thing, then I give up. Are the skylight setting definitely the same?..

16

Im not sure. how do I check that?

17

I tried making them exactly the same but it didn’t seem to change much so i didn’t save the changes. Any other ideas?

18

Static and stationary is a huge difference. Even after you change them, you have to build the light.

19

I did. It didn’t make much of a different besides the light looking a little different in the same areas where I shouldn’t have the shadows/light. I then changed the location to be like the skylight from my main level and built it again and nothing changed.

Another thing you can do is a ‘save as…’ and then take stuff out, that HAS to work :slight_smile:
